not sure where to put code

I have a content box under my nav-bar where I want to put a slider. When i put the short code in the content box it just displays the short code for the world to see. In the instructions it states:"Inserting a Slider into a theme Template file

Use to display a slider anywhere in your template files."

I have no idea where to put the above coding I would appreciate assistance.

and all it does is display the short code on my homepage. I have used many different sliders and they simply are not working. One slider showed the slider box and slider controls, but without the pictures I added to the slider.
